Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487456, here are decompositions:

5 + 2147487451 = 2147487456
7 + 2147487449 = 2147487456
47 + 2147487409 = 2147487456
53 + 2147487403 = 2147487456
83 + 2147487373 = 2147487456
97 + 2147487359 = 2147487456
113 + 2147487343 = 2147487456
197 + 2147487259 = 2147487456

Showing the first eight; more decompositions exist.

IPv4 address
